Numerous food consumption studies have been carried out to assess the nutritional status of various populationsin Papua New Guinea, for the purpose not only of improving their nutritional status but also of revealing their mechanisms of adapting to the local environment. However, most of the research methods applied were problematic in reliability and accuracy. This paper aims to identify appropriate ways of methodologically assessing the previous food and nutrition studies, including my own, based on the following points: (1) unit of data collection, (2) sampling of subjects, (3) time duration and timing of data collection, (4) measurement of consumed amounts of foods, (5) conversion from foods consumed to nutrients absorbed, and (6) standardization to per-person (adult male) nutrient intake.
